If there is no main flow temperature sensor, the following configuration adopts the meas-
ured value inside the controller from the boiler sensor of the current lead boiler:
Main menu > Commissioning > Extra configuration > Boiler sequence manager > Inputs > Main
flow sensor: autonomous
This variant can only be used with dual-boiler plant.
The main return temperature sensor is highly recommended in connection with a
pressureless header; but its configuration can also be deleted.
In the extra configuration, the basic configuration can be complemented and/or
amended.
